Disclosed is an ignition apparatus for an internal combustion engine. The ignition apparatus includes a spark plug, an ignition coil and a controller. The spark plug has an auxiliary combustion chamber in which a discharge gap is arranged. The ignition coil is configured to apply a voltage to the spark plug. The controller is configured to perform a multiple-discharge mode in which discharge is generated at least twice, with a discharge pause period intervening therebetween, across the discharge gap within a period from a compression stroke to an expansion stroke of the internal combustion engine.
